As a matter of interest ... the actual cup size is determined by your measurement  from your centre breastbone around to the point where you can feel rib again. Hence I am an E cup because I'm quite wide but my Mum whose a DD cup is heaps bigger than me. This measurement doesn't really change even if you lose\gain weight. Wearing a smaller cup size will cause the underwire to dig into the breast and be uncomfortable.  

I've had this happen several times when I've installed new EP's or Stuff Packs the game changes the name of a sim to something completely random. It drives me crazy to the point where I have a new neighbourhood I'm too scared to start playing until I get Freetime. I know you can change it with Simpe (I've never done it tho) but I want to know if there is a way to prevent it in the first place. Thanks
